Abstract:
Objective To improve the quality of medical image and enhance the image in range of frequency area.Methods Images were enhanced by adopting the arithmetic of Laplacian and Sobel,and using image multiplication and addition.The effects were compared.Results After being transformed in Laplacian,the interior frame of original image turned to be obvious and the original image was led into much noise simultaneously.In comparison with the former one,the image would be more smooth after being transformed by Sobel.Treated by average filter,the influence of noise and tiny detail would be reduced.Conclusion The toolbox of Matlab can simplify the program work,which provides a method for medical image processing.
